Korloy DCGT11T308-AK H01 Polished Insert for Aluminum & Copper, R0.8 (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy DCGT11T304-AK H01 (ANSI Standard: DCGT 32.52) is engineered for high-efficiency semi-finishing and finishing of non-ferrous materials. Featuring a robust 0.8mm (1/32") nose radius, this insert offers the highest edge strength in the DCGT 11T3 range. The AK (Aluminum Knight) chipbreaker is world-renowned for its mirror-polished surface, which eliminates chip welding (Built-Up Edge) even at high temperatures. Built with H01 uncoated micro-grain carbide, it provides the sharpest edge and the cleanest cuts for Aluminum, Brass, and high-performance Plastics.
Maximum Feed Rates: The R0.8 radius allows you to push higher feed rates while maintaining a stable cut and excellent surface finish, making it perfect for larger diameter non-ferrous parts.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | DCGT11T308-AK |
| ANSI Code | DCGT 32.52 |
| Grade | H01 (Mirror-Polished Uncoated Carbide) |
| Nose Radius | 0.8 mm (Enhanced Edge Stability) |
Core Performance Benefits:
- Superior Chip Evacuation: The polished rake face ensures chips slide off instantly, preventing surface scratching and tool overheating.
- Extended Tool Life: The R0.8 radius dissipates heat more effectively than smaller radii, significantly increasing tool life in continuous high-speed cuts.
- Extreme Surface Gloss: Capable of achieving highly reflective "mirror" finishes on Aluminum 6061, 7075, and various Copper alloys.
- Vibration Resistance: The robust edge design helps stabilize the cut during semi-roughing or when taking deeper passes in soft materials.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum Alloys | 350 - 1100 m/min | 0.15 - 0.45 mm/rev | 0.5 - 4.5 mm |
| Copper / Yellow Brass | 150 - 650 m/min | 0.10 - 0.35 mm/rev | 0.3 - 3.0 mm |
| High-Performance Plastics | 100 - 550 m/min | 0.20 - 0.50 mm/rev | 0.8 - 6.0 mm |
Compatible Tool Holders:
Works with all standard 55-degree diamond tool holders for 11T3 inserts:
- External Turning: SDJCR/L 1616H11 / 2020K11 / 2525M11
- Precision Boring: S16Q-SDUCR11 / S20R-SDUCR11 / S25S-SDUCR11
Pro Tip: Why choose the R0.8 Radius?
Selecting the best tip for your non-ferrous turning:
Best for semi-finishing and faster stock removal. It is the most robust choice and handles interrupted cuts better than the smaller R0.2/R0.4 tips.
Best for pure finishing. It creates lower radial pressure, which helps maintain precision on smaller, less stable machines or thin workpieces.
Machinist's Insight: If you are working on large Aluminum diameter shafts, the DCGT11T308 is the superior choice because it allows you to increase your feed rate without the tip wearing out prematurely.
Packaging: 10 pieces per box.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
